目的 测试多成分技术干预对于减少久坐、超重大学员工每日久坐时间和改善心脏代谢疾病风险的功效。设计盲法、随机对照试验。背景为美国东南部一所大型大学。参与者 49 名从事久坐工作的中年人（主要是女性）久坐和超重成年人参加了这项研究。共有 40 名参与者完成了这项研究。 干预措施 参与者被随机分为：(1) 干预组（N=23；47.6+9.9 岁；94.1% 女性；33.2+4.5kg/m(2)）； (2) 或等候名单对照组（N=17；42.6+8.9 岁；86.9% 女性；31.7+4.9kg/m(2)）。干预组接受了基于理论、通过互联网提供的课程、工作中的便携式踏板机和计步器，为期 12 周。等待名单对照组维持他们的行为 12 周。 结果测量 在基线和干预后（12 周）测量主要（通过 StepWatch 客观测量的久坐和体力活动行为）和次要（心率、血压、身高、体重、腰围、身体脂肪百分比、心肺健康、空腹血脂）结果。干预后还评估了包括干预依从性和过程评估措施在内的探索性结果。结果与对照组相比，干预组减少了每日静坐时间（平均变化（95％CI）：-58.7 分钟/天（-118.4 至 0.99；p
Objectives To test the efficacy of a multicomponent technology intervention for reducing daily sedentary time and improving cardiometabolic disease risk among sedentary, overweight university employees.Design Blinded, randomised controlled trial.Setting A large south-eastern university in the USA.Participants 49 middle-aged, primarily female, sedentary and overweight adults working in sedentary jobs enrolled in the study. A total of 40 participants completed the study.Interventions Participants were randomised to either: (1) an intervention group (N=23; 47.6+9.9years; 94.1% female; 33.2+4.5kg/m(2)); (2) or wait-list control group (N=17; 42.6+8.9 years; 86.9% female; 31.7+4.9kg/m(2)). The intervention group received a theory-based, internet-delivered programme, a portable pedal machine at work and a pedometer for 12weeks. The wait-list control group maintained their behaviours for 12weeks.Outcome measures Primary (sedentary and physical activity behaviour measured objectively through StepWatch) and secondary (heart rate, blood pressure, height, weight, waist circumference, per cent body fat, cardiorespiratory fitness, fasting lipids) outcomes were measured at baseline and postintervention (12weeks). Exploratory outcomes including intervention compliance and process evaluation measures were also assessed postintervention.Results Compared to controls, the intervention group reduced daily sedentary time (mean change (95%CI): -58.7min/day (-118.4to 0.99; p
